Description

Technical Field

[0001] This invention relates to the technical field of laminated boards, specifically to a laminated board that avoids arching. Background Technology

[0002] As the name suggests, composite board refers to building board made of two or more layers of materials glued together. Specifically, it refers to processing different materials into material layers to meet manufacturing requirements, applying glue between the material layers, and then processing them through pressing and heating to form a type of board with comprehensive performance that is different from traditional boards.

[0003] Composite panels, as a new type of environmentally friendly building material, have many advantages such as high strength, stable quality, and moisture and corrosion resistance. They are widely used in building exterior wall insulation, decorative wall panels, and sound insulation wall panels.

[0004] The laminated plates used under the current technological background still have certain drawbacks, such as:

[0005] 1. When assembling existing composite slabs on buildings, in order to enhance the aesthetics of the building, adjacent composite slabs usually need to be fitted and overlapped together, or connected by connecting strips to reduce the gap after the composite slabs are assembled. However, due to the influence of external hot and cold environments, composite slabs are easily deformed by thermal expansion and contraction. As a result, the assembled composite slabs do not have adaptive self-adjustment space, and are prone to arching due to compression, which affects the flatness of the composite slab assembly and also affects the stability and reliability of the composite slab assembly.

[0006] 2. In existing composite slab assembly, the required composite slab size and specifications vary depending on different design requirements. Composite slab assembly uses connecting strip assemblies to fix adjacent composite slabs. However, existing connecting strip assemblies are usually set up to match composite slabs of general size. That is, when dealing with the adjustment and cutting of composite slabs, the existing composite slab connection mechanism cannot be adjusted accordingly, which affects the applicability of composite slab assembly and makes it inconvenient to operate and use.

[0007] Therefore, we propose a composite slab that avoids arching in order to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a composite slab that avoids arching, thereby solving the problems mentioned in the background art, such as the lack of adaptive self-adjustment space, the tendency of composite slabs to be squeezed and arched after assembly, and the inability of the connecting mechanism to make adaptive adjustments during the assembly of composite slabs, which affects the scope of application.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a composite slab that avoids arching, comprising:

[0010] An assembly frame, which is embedded in and fixedly connected to the wall of the building;

[0011] Also includes:

[0012] A strip connecting frame is fixedly installed on the longitudinal frame plate in the assembly frame, and it is used for the assembly connection between two adjacent composite plate bodies;

[0013] The pressure-locking mechanism is arranged at equal intervals from top to bottom within the tube frame cavity of the strip connecting frame. The pressure-locking mechanism forms a sliding structure within the tube frame cavity of the strip connecting frame. It can make appropriate sliding adjustments to accommodate the composite plate body of different specifications and sizes. It is also equipped with an adaptive self-adjusting space to prevent the composite plate body from deforming and arching due to thermal expansion and contraction.

[0014] Preferably, both ends of the rear tube wall of the strip connecting frame are bent to form an integrated plate frame, and the plate frame is fixedly connected to the longitudinal frame plate in the assembly frame by bolts. Both sides of the opening in the strip connecting frame are bent to form an integrated baffle, and the cross-sectional shape of the baffle is a right triangle.

[0015] The strip-shaped connecting frame has positioning holes spaced at equal intervals in the middle of the rear tube wall.

[0016] Preferably, the pressure-type locking mechanism includes a housing, a locking bolt, a locking post, and a pressure member. The housing is slidably connected to the tube frame cavity of the strip connecting frame. A driving block is slidably connected inside the housing cavity of the housing, and inclined sidewalls are provided on both the left and right sides of the driving block. A locking bolt is rotatably connected to the middle of the front housing wall of the housing through a bearing, and the bolt body of the locking bolt is threadedly connected to the tube groove wall of the driving block.

[0017] The left and right sides of the shell base are each connected to a locking pin in a telescopic sliding manner, and a first spring is installed at the connection between the locking pin and the shell base.

[0018] The narrow section of the locking post is slidably connected to a pressing member within its cavity, and a second spring is installed at the connection between the pressing member and the locking post.

[0019] Preferably, a pin is telescopically slidably connected to the middle part of the sub-shell portion in the housing body, and a third spring is installed at the connection between the pin and the sub-shell portion in the housing body;

[0020] The pin head is hemispherical, and the hemispherical head end of the pin is connected to the positioning hole by a snap-fit ​​mechanism.

[0021] Preferably, the middle part of the side wall of the wide part of the locking column is provided with an integrated auxiliary block, and the end of the auxiliary block is provided with an inclined side wall, and the inclined side wall of the auxiliary block is pressed and fitted against the inclined side wall of the driving block.

[0022] Preferably, the narrow part of the locking column slides along the groove in the strip connecting frame to form a sliding structure on the strip connecting frame, and the wide part of the locking column is connected to the tube frame cavity wall of the strip connecting frame by pressing and fitting.

[0023] Preferably, the locking post drives the pressing member to form a synchronous sliding structure, and the pressing plate part of the pressing member abuts against the side wall of the composite plate body, and the pressing plate part of the pressing member is fixedly connected to the side wall of the composite plate body by bolts.

[0024] Preferably, the locking bolt cap slides along the groove in the baffle plate to form a sliding structure, and the locking bolt cap is connected to the groove wall of the baffle plate by pressing and fitting, and a strip cover plate is snapped into the groove of the baffle plate and fixedly connected by bolts.

[0025] The baffle plate and the plate frame are clamped together to limit the position of the composite plate body.

[0026] Compared with the prior art, the beneficial effects of the present invention are: the anti-arching composite plate can be adapted to the specifications and dimensions of the composite plate when assembling composite plates of different sizes, effectively improving the applicability of composite plate assembly, providing adaptive self-adjustment space after the composite plate is assembled, avoiding arching after the composite plate is deformed and squeezed, and ensuring stability and reliability in the assembly of composite plates;

[0027] 1. It is equipped with a strip connecting frame and a pressure-locking mechanism. The pressure-locking mechanism is evenly spaced from top to bottom in the tube frame cavity of the strip connecting frame. The pressure-locking mechanism forms a sliding adjustment structure in the tube frame cavity of the strip connecting frame. The pressure-locking mechanism can be freely added or removed in the tube frame cavity of the strip connecting frame. The lower ends of the strip connecting frame and the baffle plate can be freely cut. When assembling composite plates of different specifications and sizes, it can be adapted to the specifications and sizes of the composite plates and freely adjusted. This effectively improves the applicability of composite plate assembly. In addition, the cutting method and the addition or removal of the pressure-locking mechanism ensure the convenience of adjustment operation.

[0028] Furthermore, the rear tube wall of the strip connecting frame is provided with positioning holes at equal intervals. The middle part of the sub-shell in the housing body is slidably connected with a pin. After the sliding adjustment of the pressure-type locking mechanism, the elastic deformation of the third spring is used to reset it, so that the hemispherical nail head of the pin engages with the corresponding positioning hole. This realizes the automatic positioning process after the adjustment of the pressure-type locking mechanism. The pressure-type locking mechanism is positioned in the tube cavity of the strip connecting frame through a convenient operation method, ensuring the stability and reliability of the composite plate assembly and avoiding positional movement that would affect the uniform force on the composite plate in the subsequent process.

[0029] 2. It is equipped with a locking pin and a stop plate. The locking pin is threadedly connected to the drive block, and the sliding fit between the inclined side wall of the drive block and the inclined side wall of the auxiliary block is used to make the locking pin drive the pressing part to slide out. Then, the pressure plate part of the pressing part presses against and fixes to the side wall of the composite plate body. The locking pin squeezes the stop plate, so that the stop plate and the plate frame part cooperate to clamp and position the composite plate body, realizing convenient assembly of the composite plate and ensuring the reliability of the composite plate after assembly.

[0030] Furthermore, after the locking column is driven to slide out, the wide part of the locking column is pressed against and fitted against the tube frame cavity wall of the strip connecting frame. Through the setting of the linkage structure, the self-locking treatment of the pressing locking mechanism is realized simultaneously when the composite plate body is pressed and fixed, making the operation more convenient.

[0031] Furthermore, a pressure member is slidably connected within the cavity of the narrow section of the locking column, and a second spring is installed between the two. When the composite plate body deforms due to thermal expansion and contraction, the cylindrical part of the pressure member slides and adjusts within the cavity of the narrow section of the locking column, and is elastically supported by the second spring. This provides adaptive self-adjustment space after the composite plate is assembled, preventing arching after deformation and compression of the composite plate, and ensuring the flatness of the assembled composite plate.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figure 1-9 The present invention provides a technical solution: a composite plate that avoids arching, including an assembly frame 1, a strip connecting frame 2, and a pressure-type locking mechanism 4.

[0044] Before the composite slab that prevents arching is assembled, the assembly frame 1 is assembled from materials such as wood or aluminum (the installation method on the building wall is existing technology and is not described in detail in the accompanying drawings). It is divided into two parts: horizontal frame plate and vertical frame plate, which are inlaid and fixedly connected to the building wall. According to the specifications and dimensions of the vertical frame plate in the assembly frame 1, the pressure-locking mechanism 4 is added, reduced and its position is adjusted. The strip connecting frame 2, the composite slab body 3 and the baffle plate 14 are cut and adjusted in sequence.

[0045] When adding, removing, or adjusting the position of the pressure-locking mechanism 4, it should be able to make appropriate sliding adjustments to accommodate composite plate bodies 3 of different specifications and sizes. Specifically, according to the attached... Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the pressure-locking mechanism 4 is placed in a movable state within the tube frame cavity of the strip connecting frame 2 after installation. It is arranged at equal intervals from top to bottom within the tube frame cavity of the strip connecting frame 2. Since the pressure-locking mechanism 4 forms a sliding structure within the tube frame cavity of the strip connecting frame 2 and also forms a disassembly structure on the strip connecting frame 2, and since the housing body 5 is movably locked within the tube frame cavity of the strip connecting frame 2 after installation, the number of pressure-locking mechanisms 4 can be increased or decreased according to usage requirements, and the housing body 5 can slide within the tube frame cavity of the strip connecting frame 2, that is, the pressure-locking mechanism 4 slides to the corresponding position within the tube frame cavity of the strip connecting frame 2.

[0046] Since the cap of the locking bolt 7 is movably locked in the groove of the baffle plate 14, and the narrow part of the locking post 8 is movably inserted into the groove of the strip connecting frame 2, when the pressure-type locking mechanism 4 slides and adjusts in the tube frame cavity of the strip connecting frame 2, the cap of the locking bolt 7 slides and adjusts along the groove of the baffle plate 14 on the baffle plate 14, and the narrow part of the locking post 8 slides and adjusts along the groove of the strip connecting frame 2 on the strip connecting frame 2;

[0047] Since the rear shell wall cavity of the shell base 5 is jammed and fixedly connected to the secondary shell part by bolts, the pin 12 is movably locked in the groove of the secondary shell part in the shell base 5 after installation. The pin head part moves through the groove wall of the secondary shell part in the shell base 5 and extends outward, so that the pin 12 is positioned on the secondary shell part in the shell base 5 in a movable state.

[0048] Because the head of the pin 12 is hemispherical, a third spring 13 is installed at the connection between the pin 12 and the sub-shell of the housing 5. After installation, the third spring 13 is movably inserted into the slot of the sub-shell in the housing 5. One end of the spring 13 is movably inserted into the spring chamber of the pin 12, pressing against the wall of the spring chamber, and the other end presses against the end cap (the end cap is fixedly connected to the slot opening of the sub-shell in the housing 5 by bolts). Furthermore, because the rear tube wall of the strip connecting frame 2 has positioning holes 203 evenly spaced from top to bottom, the positioning holes 203 are aligned with the hemispherical head end of the pin 12. When the locking mechanism 4 is adjusted to slide, the hemispherical head of the pin 12 loses its engagement with the current positioning hole 203, causing the pin 12 to slide and retract in the middle of the sub-shell in the housing 5, and causing the third spring 13 to be compressed and undergo elastic deformation. After the locking mechanism 4 is adjusted to slide, the elastic deformation of the third spring 13 is used to reset, causing the pin 12 to slide out in the middle of the sub-shell in the housing 5, and causing the hemispherical head of the pin 12 to re-engage with the next positioning hole 203, thus completing the positioning after the locking mechanism 4 is adjusted to slide.

[0049] When cutting and adjusting the strip connecting frame 2, the composite plate body 3, and the baffle plate 14 in sequence, specifically, according to the attached... Figure 1 , Figure 2 and Figure 4 As shown, the strip connecting frame 2 is first cut from its lower end to make its specifications and dimensions match the longitudinal frame plate in the assembly frame 1. Since the left and right ends of the rear tube wall of the strip connecting frame 2 are bent to provide an integrated plate frame part 201, the plate frame part 201 is set in a corresponding parallel state with the rear tube wall of the strip connecting frame 2. After the strip connecting frame 2 is installed, the rear tube wall and the plate frame part 201 are snapped onto the longitudinal frame plate in the assembly frame 1, and the plate frame part 201 is fixedly connected to the longitudinal frame plate in the assembly frame 1 by bolts, so that the plate wall of the plate frame part 201 is flush with the plate wall of the longitudinal frame plate in the assembly frame 1.

[0050] Next, the composite plate body 3 is cut to make its dimensions match the longitudinal frame plate in the assembly frame 1. Since the strip connecting frame 2 is fixedly placed on the longitudinal frame plate in the assembly frame 1 and is set in a perpendicular state to the longitudinal frame plate in the assembly frame 1, it is used for the assembly connection between two adjacent composite plate bodies 3. Since the longitudinal section of the transverse frame plate in the assembly frame 1 is "L" shaped, the upper and lower limit assembly of the composite plate body 3 is carried out through the structural shape of the transverse frame plate in the assembly frame 1, so that the composite plate body 3 is placed in the frame cavity of the assembly frame 1 after placement. Its upper and lower sides are pressed against the upper and lower transverse frame plates of the assembly frame 1 respectively, and its rear sidewall is pressed against the plate frame part 201. It is placed in the gap between the two strip connecting frames 2, and its left and right sides correspond to the tube frame sidewalls of the left and right strip connecting frames 2 respectively.

[0051] Next, the baffle plate 14 is cut from its lower end so that the size of the baffle plate 14 matches the strip connecting frame 2. Since the baffle plate 14 is set in a parallel state with the plate frame part 201 after it is installed, the composite plate body 3 is limited by the baffle plate 14 and the plate frame part 201 by clamping.

[0052] To prevent arching, the composite slabs should be assembled according to the attached... Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the strip connecting frame 2 is set in a square tube structure, and its front tube wall is set in an open state. The left and right sides of the opening in the strip connecting frame 2 are bent and set with an integrated baffle part 202. The middle of the baffle plate 14 has a through groove. Since the bolt body of the locking bolt 7 is fixedly clamped with a bearing, after the locking bolt 7 is installed, it is clamped on the front shell wall of the housing body 5 along with the bearing. The bolt cap is placed on the outside of the housing body 5, and moves through the gap between the two baffle parts 202. It is movably clamped in the groove cavity of the groove in the baffle plate 14. By using an external wrench, the locking bolt 7 is manually driven, so that the locking bolt 7 is connected to the middle of the front shell wall of the housing body 5 by the bearing.

[0053] Since the driving block 6 has a through-shaped groove in the middle, after the locking bolt 7 is installed, the bolt body is movably inserted into the cavity of the housing 5 and into the groove of the driving block 6. The bolt body is threadedly connected to the groove wall of the driving block 6. Since the driving block 6 is movably locked in the cavity of the housing 5 after installation, the locking bolt 7 is driven to rotate. Through the threaded connection between the locking bolt 7 and the driving block 6, the driving block 6 slides in the cavity of the housing 5.

[0054] Because the cross-sectional shape of the baffle part 202 is a right-angled triangle, it serves a supporting and reinforcing function according to its structural form. The baffle part 202 is set vertically at the opening of the strip connecting frame 2, and the two baffle parts 202 are set in opposite directions to each other, without completely blocking the opening of the strip connecting frame 2, leaving a gap between them. Furthermore, because the baffle plate 14 has an integrated protruding part in the middle of the side facing the strip connecting frame 2, after the baffle plate 14 is installed, the protruding part is inserted into the two baffle parts on the left and right sides. At the gap between the baffle portions 202, the inclined wall of the protruding part abuts against the inclined wall of the baffle portion 202. When the locking bolt 7 is screwed, the locking bolt 7 and the driving block 6 are relatively displaced through the threaded connection between the driving block 6 and the locking bolt 7, so that the bolt cap in the locking bolt 7 is connected to the groove wall of the slide groove in the baffle plate 14 by abutting against it, and the front shell wall of the housing 5 is pressed against the baffle portion 202, thus completing the placement and locking of the baffle plate 14, which is used to limit the placement of the composite plate body 3.

[0055] Because the cross-section of the drive block 6 is an isosceles trapezoidal structure, and inclined sidewalls are provided on both the left and right sides, the inclined sidewalls on the left and right sides are opposite and arranged in a figure-eight shape. Also, because an integrated auxiliary block 801 is provided in the middle of the sidewall of the wide column of the locking column 8, it is set in a vertical state and its end is provided with an inclined sidewall. The inclined sidewalls of the two auxiliary blocks 801 are set in opposite directions. After the locking column 8 is installed, the auxiliary block 801 moves through the sidewall groove of the housing 5 and moves into the housing cavity of the housing 5. The inclined sidewall is pressed against and fits against the inclined sidewall of the drive block 6. After the drive block 6 is driven to slide, the inclined sidewall of the drive block 6 and the inclined sidewall of the auxiliary block 801 push the auxiliary block 801 to move through the sliding cooperation between them.

[0056] Since through slots are provided on the side walls of the left and right pipe racks of the strip connecting frame 2, and the slots are communicated with the pipe rack cavities, and the lower ends of the slots are open, and since locking columns 8 are provided in the middle of the left and right side walls of the housing body 5, the locking columns 8 are of a cylindrical structure, and their cross-sections are of a "convex" shape structure, which are divided into two parts, a narrow part column body and a wide part column body. After the locking columns 8 are installed, the wide part column bodies are movably clamped in the wall slots of the housing body 5, and the narrow part column bodies are movably inserted through the slots in the strip connecting frame 2 and extend outwards. Moreover, since a first spring 9 is installed at the connection between the locking column 8 and the housing body 5, the first spring 9 is sleeved outside the auxiliary block 801 in a movable state, one end of which is inserted into the spring chamber of the wide part column body of the locking column 8 and is fixedly connected to the spring chamber wall by a bolt, and the other end of which is inserted into the spring chamber of the wall slot of the housing body 5 and is fixedly connected to the spring chamber wall by a bolt. After the auxiliary block 801 is pushed, the locking column 8 slides out in the middle of the side wall of the housing body 5, that is, the left and right two locking columns 8 slide out in opposite directions, and the first spring 9 is pulled to generate elastic deformation;

[0057] Since the diameter dimension of the wide part column body of the locking column 8 is larger than the width dimension of the slot in the strip connecting frame 2, after the locking column 8 is driven to slide out, the wide part column body of the locking column 8 is connected to the wall of the pipe rack cavity of the strip connecting frame 2 in a manner of pressing and fitting, and the pressing type locking mechanism 4 is locked and installed in the pipe rack cavity of the strip connecting frame 2;

[0058] Since a limiting ring is fixedly connected to the end of the narrow part column body of the locking column 8 by a bolt, and since the pressing member 10 is composed of two parts, a cylindrical part and a pressing plate part, and the cross-section of the cylindrical part is of a "T" shape structure. After the pressing member 10 is installed, the cylindrical part is movably inserted through the limiting ring of the narrow part column body of the locking column 8 and is movably inserted into the column cavity of the narrow part column body of the locking column 8, so that the pressing member 10 is positioned on the locking column 8 in a movable state. When the locking column 8 is driven to slide out, the pressing member 10 is synchronously extended and slid;

[0059] Since the pressing plate part of the pressing member 10 is clamped and fixedly connected to the end of the cylindrical part by a bolt, and the pressing plate part is arranged perpendicular to the cylindrical part, after the pressing member 10 slides out, the pressing plate part is pressed and abutted against the side wall of the laminated plate body 3, and the pressing plate part of the pressing member 10 is fixedly connected to the side wall of the laminated plate body 3 by a bolt to perform pressing and limiting of the laminated plate body 3, that is, to assist in the fixed installation of the laminated plate body 3;

[0060] Since a second spring 11 is installed at the connection between the pressing member 10 and the locking post 8, the second spring 11 is movably inserted into the spring chamber of the cylindrical part of the pressing member 10 after being installed. One end of the spring 11 presses against the spring chamber wall of the cylindrical part of the pressing member 10, and the other end presses against the column cavity wall of the narrow part of the locking post 8. When the locking post 8 drives the pressing member 10 to slide, it presses against the side wall of the composite plate body 3, causing the pressing member 10 to slide and contract in the column cavity of the narrow part of the locking post 8, and causing the second spring 11 to be squeezed and undergo elastic deformation.

[0061] Because the slide groove in the baffle plate 14 is snapped and fixedly connected to the strip cover plate 1401 by bolts, the strip cover plate 1401 provides support and reinforcement for the slide groove in the baffle plate 14 and provides protection for the bolt cap in the locking bolt 7.

[0062] Based on the above, the pressure-type locking mechanism 4 is provided with an adaptive self-adjusting space. When the composite plate body 3 is deformed due to thermal expansion and contraction, the pressure member 10 is adaptively slidably adjusted in the column cavity of the narrow column in the locking column 8 by the elastic support of the second spring 11, so as to avoid the composite plate body 3 from being squeezed and arched.

[0063] This is the entire working process for preventing the composite slab from arching. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0064] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
